Red Kites
The frosty air is full of swooping wings and harsh cries. At a secret location somewhere in West Wales it is feeding time for more than 100 red kites.
With a wingspan of nearly two metres, but a relatively small body, these predators are extremely agile and their brilliant chestnut red plumage and forked tails make them a dazzling sight.
Seven birds were first fed here in 1999 but during last month's bitter weather the helper who serves 28lb (13kg) of meat off-cuts for them each day saw as many as 300.
"They come rushing at me," said the woman, who does not wish to be identified in order to safeguard the location. "I protect myself with an umbrella but if it's too windy I wear a crash helmet"
"Last week one walloped me on the bottom - it was sticking out more than I thought!"
The display is testament to conservation efforts after the birds came close to dying out. There are now more than 1,000 breeding pairs in the UK. Other European countries, where populations are at risk from poisoning and pesticides, are studying the success story.
